High, Persistent Breast Cancer Mortality in Sub‑Saharan Africa: 7‑Year ABC‑DO Cohort Reveals Major Survival Gaps and Actionable Targets

High, Persistent Breast Cancer Mortality in Sub‑Saharan Africa: 7‑Year ABC‑DO Cohort Reveals Major Survival Gaps and Actionable Targets

A 7‑year follow-up of 2,153 women in the ABC‑DO cohort shows poor breast cancer survival in much of sub‑Saharan Africa, with 5‑year crude survival 40% and marked between-country and racial disparities; reaching WHO stage downstaging targets and improving treatment access could cut deaths by about a third.
SUPREMO Ten-Year Results: Chest‑Wall Irradiation After Mastectomy Lowers Local Recurrence but Does Not Improve 10‑Year Survival in Intermediate‑Risk Breast Cancer

SUPREMO Ten-Year Results: Chest‑Wall Irradiation After Mastectomy Lowers Local Recurrence but Does Not Improve 10‑Year Survival in Intermediate‑Risk Breast Cancer

The SUPREMO randomized trial found that postmastectomy chest‑wall irradiation reduces chest‑wall recurrence but does not improve 10‑year overall survival for intermediate‑risk breast cancer; a large real‑world analysis supports no overall survival benefit except possibly for pT3N0 disease.
